Specifications

1,Dry Sieve Test Apparatus
2,To determine the apparent/equivalent opening size of a geotextil

Application

Geotextile Opening Size Tester is used todetermine the apparent/equivalent opening size of a geotextile by sieving sizedglass beads through the geotextile, using the dry-sieve principle. A geotextilespecimen is placed in a sieve frame and sized glass beads are placed on thegeotextile surface. The geotextile and frame are shaken laterally so that thejarring motor will induce the beads to pass through the test specimen. Theprocedure is repeated on the same specimen with various sized glass beads untilits apparent opening size has been determined. The apparent opening size (O₉₀)of the geotextile corresponds to a specified size of graded glass beads passed(d₉₀).

Q: Axial fan installed directly on the wall exhaust, how to determine its wind pressure?: If accurate measurements are required, it is necessary to connect a duct and then use a special calibration instrument to measure it.

Q: Is the fan pressure static pressure?: Refers to the pressure generated when the air flow, as long as the duct air flow has a certain dynamic pressure, its value is always positive.

Q: 380V axial fan has five lines how to take?: If it is three-phase 380V axial fan, the coil DC resistance is not the same, indicating that the motor is broken, can not be wired

Q: Is the centrifugal fan plugging the air inlet motor?: If it is to take the energy saving way to block the air intake to save electricity, it would be better to directly change the centrifugal fan control mode is simple and convenient

Q: What are the models and specifications of the axial fans?: Axial fans are often used in situations where the flow rate is high and the pressure is low.

Q: What is the operation of centrifugal fans and axial fans?: When the impeller rotates, the gas enters the impeller from the inlet of the air inlet, and the energy of the gas is raised by the pushing of the blades on the impeller and then flows into the guide vane. The guide vanes change the deflected airflow into axial flow and introduce the gas into the diffuser tube, further converting the kinetic energy of the gas into pressure energy, and finally introducing the working line.

Q: What are the characteristics of high-pressure axial fans?: 2. High reliability When the use of changes, the machine can still operate safely. In addition to the impeller, the high pressure blower has no other action, so the reliability is almost free of maintenance. It has the following advantages: high compression ratio; low bearing running temperature; long life of lubricating grease; maintenance-free.

Q: Fire high temperature exhaust fan is a centrifugal fan?: Identify the axial fan and centrifugal fan, first from the two air flow to look. The air of the axial fan is 180 degrees

Q: How to see the axial fan is good or bad?: Axial fans are mainly composed of fan impellers and housings. The structure is simple but the data is very high.

Q: What types of fans are usually divided into?: (Hereinafter referred to as push-in fan) and explosion-proof motor placed outside the flow channel or in the flow channel, the explosion-proof motor placed in the explosion-proof sealing chamber of the extraction of local fan (hereinafter referred to as the extraction fan ).
